An autodidact without notational skills, he was considered by his contemporaries to be the best living ragtime pianist. In 1916 he was involved in a massive legendary
ragtime piano competition in St. Louis whereby there were 68 participants. Amongst these included the best in St. Louis, to whit Thomas Million Turpin
and all of the famous Police Gazette contest players. He was declared the Missouri State Champion after a two week competition.

and published by the Syndicate Music Company, St. Louis, Missouri and he is still remembered for his Delmar Rag
composed sometime in the 1910's.
